REFLECTOR-SUPPORTED LIGHT-SOCKET MOUNTING.

Application filed April 22, v192v. Serial No.- 185,803.

This invention relates to the mounting of a light bulbsupporting'socketed plug upon a reflector. a The chief objectof theinvention is to detachably but rigidly mount a light bulb sup portingsocketed plug upon a reflector such that the filament is positioned inpredetermined relation to'the reflector focus or refiecting surface. 4The chief feature of the invention consists in the provision of arefiectorsupported plug receiving sleeve and yieldingly associatingtherewith a light bulb supported socketed plug, said sleeve and plughaving a detach- 'able and pin and slot connection for rigidly butdetachably connecting the same for predetermined positioning.

The full nature of the invention will be understood from. theaccompanying drawin'gs and the following description and claims:

Fig. 1 is an elevational View of one form of the invention. Fig. 2 is alongitudinal sectional view taken on line 22 of Fig. 1 and in thedirection of the arrows. Fig, 3 1s a longitudinal central sectional viewof a modified form of the invention. Fig 4 is an elevational' view ofthe reflector supported socket support shownin Fig, 3. Fig. 5 is anelevational view of the light bulb supporting socketed plug shown inFig. 3.

In the drawings IO'indicates a reflector rigidly mounting in its centralaperture 11 a sleeve 12. Said sleeve includes apair of bayonet orJ-slots 13 in opposed or diametrical relation. The sleeve is open atboth ends and slidably and rotatably receives a light bulb supportingsocketed plug 14 which includes the J-slots 15 at its forward end toreceive a. light bullo 16 having the co-op ,erating anchoring pins 1-7and including a filament 18 which is adapted to coincide with the focusof the reflector or to be positioned in predetermined relation withreference to the reflecting surface. i

The plug supports a pair of radially-extending pins 19 and herein thesame are shown separated and oppositelyextending,

said pins being receivable by the sleeve slots 13 for anchoring the plug14 in the sleeve and in predetermined relation to the reflector 10.Bearing against pins 19 is awasher or retaining ring 20 and interposedbetween said ring and the anchoring flange 21 of the sleeve is 'acoilspring 22 for normally maintaining pins 19 seated in the oifset portion93 of the J orbayonet slot 13 for yieldingly retaining the plug inpredetermined position in the sleeve.

In Fig. 3 a modified form of the invention is illustrated,-,and hereinthe reflector 10 supports a sleeve 112 in turn supporting aspring 22 anda washer or ring 20, said sleeve 112 having the J-slot 113 with theanchoring ofl'set seat portion 123 therein to receive tongues 119 struckfrom the plug 114 at 109. Said plug 114 includes a bayonet slot 115 for.receiving the pins 17 of the light bulb 16. In this form of theinvention the slot receivable pinsare formed integral with and from theplug exterior shell portion. The invention claimed is: I

1. In a he d lamp construction, the combination of areflector supportedsleeve, 9. plug slidably and rotatably receivable there-' by, said plugincluding in one end a light bulb receiving socket, a plurality ofanchoring slots in said sleeve, a plurality of cooperating pins seatablein said slots for detachably connecting the plug and sleeve, a

retainer slidably mounted on said sleeve and retainedthereon by saidpins, and yielding means for maintaining the pin and slot connectionintact, said retainer being interposed between said pins and yieldingmeans.

'2'. A device as defined by claim '1 characterized by said pinscomprising outwardly directed projecting portions formed integral withthe plug.

- In witnesswhereof, I have hereunto aflixed my signature.
